thruputMeter check_and_cast

[Teo Iliadis]

Hey there, 

in the net80211_control example of Inet,  I have added the thruputMeter between the udp and updApp (See the print screen) . 

[udp.ipOut --> thruputMeter1.in;

 thruputMeter1.out --> udpApp[0].udpIn; ]

I have this error :

<!> Error in module (ThruputMeter) Net80211_control.host[0].thruputMeter1 (id=16) at event #4, t=0: check_and_cast(): cannot cast (cMessage *)Net80211_control.host[0].thruputMeter1.RegisterProtocol to type 'cPacket *'.

I have tried to change the Thruputmeter.cc the HandleMessage functoin but nothing. 

Please if somebody knows how to use the thruputMeter , give me some help!

Thx in advance.
